Product details
Overview
P6SMB150AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 158 V maximum breakdown voltage (VBR), and 207 V clamping voltage (VC) at 2.9 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB150AHM3/I datasheet, P6SMB150AHM3/I pinout, P6SMB150AHM3/I application, or P6SMB150AHM3/I equivalent, this device delivers verified 600 W peak pulse power handling with 10/1000 μs waveform, AEC-Q101 qualification, halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level surge protection design.
Technical Context
The P6SMB150AHM3/I operates as a unidirectional clamping TVS diode with glass-passivated junction and fast response time (<1 ns), enabling suppression of transient overvoltages before sensitive downstream components (e.g., MOSFET gates or MCU I/O) are damaged. Its cathode-band polarity marking aligns with standard SMB layout conventions.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 600 W pulse dissipation. It supports repetitive surge duty cycle ≤0.01 % and operates across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Confirmed voltage threshold where device transitions into avalanche conduction; tight 5% tolerance ensures predictable triggering. |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs transient; limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validates robustness against IEC 61000-4-5 surges. |
| IFSM (Surge Current) | 100 A - Single half-sine 8.3 ms forward surge rating; supports protection of DC power inputs against load dump events. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount footprint with 2.20 mm height and 3.94 mm length; compatible with automated pick-and-place and reflow soldering. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs and lighting modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power rail and chassis ground to shunt surge current away from regulator ICs and microcontrollers. Use Value: Limits transient voltage to ≤207 V during 600 W surges, preventing latch-up or gate oxide damage in downstream PMICs and CAN transceivers. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in PLC I/O modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Point-of-entry TVS on differential or single-ended signal lines, referenced to local ground plane. Use Value: Sub-1 ns response ensures clamping occurs before 100 ns edge of fast-rising EFT bursts, preserving signal integrity and ADC accuracy. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Secondary-side protection on PoE-powered Ethernet switch ports and DSL line cards subjected to induced lightning surges. IC Role / Device Role / Timing Role: Standoff-clamp TVS on DC bias lines feeding PHY ICs and magnetics, coordinated with upstream GDT or MOV. Use Value: 128 V VWM provides sufficient margin above 57 V PoE+ nominal, while 207 V VC avoids exceeding PHY absolute maximum ratings. |
Use Scenario: Snubbing inductive kickback from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Freewheeling TVS across motor terminals or H-bridge outputs to absorb back-EMF energy. Use Value: 100 A IFSM rating handles repeated 8.3 ms motor stall currents; low incremental resistance minimizes clamping overshoot during commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/5B | Same VWM/VBR/VC specs; SMA package (smaller footprint, higher RθJA = 140 °C/W); non-AEC-Q101, commercial-grade only. | Limited to non-automotive industrial or consumer use due to lack of automotive qualification and reduced thermal margin. | Select when board space is constrained and automotive qualification is not required; verify thermal derating at full 600 W pulse. |
| 1.5SMC150AHE3_A/H | Same electrical specs; SMC package (larger than SMB, RθJA = 65 °C/W); AEC-Q101 qualified; halogen-free RoHS. | Better thermal performance supports higher repetition rates; larger footprint may conflict with dense layouts. | Prefer for high-duty-cycle surge environments (e.g., engine control units) where SMB thermal limits are marginal. |
Compared with SMAJ150A-E3/5B and 1.5SMC150AHE3_A/H, the P6SMB150AHM3/I uniquely balances AEC-Q101 qualification, SMB footprint compactness, and MSL Level 1 process compatibility - making it optimal for space-constrained automotive modules requiring zero-bake assembly and validated surge endurance.

FAQ
What is the clamping voltage of the P6SMB150AHM3/I at its rated peak pulse current?
The P6SMB150AHM3/I has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB150AHM3/I maintains this clamping performance across its specified operating temperature range and is validated for repetitive surge duty cycles up to 0.01 %.
Is the P6SMB150AHM3/I qualified for automotive applications?
Yes, the P6SMB150AHM3/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT) per AEC-Q101 requirements. The P6SMB150AHM3/I is approved for use in body electronics, infotainment power supplies, and sensor interfaces where automotive reliability standards apply.
What is the standoff voltage rating for the P6SMB150AHM3/I?
The P6SMB150AHM3/I has a maximum reverse stand-off voltage (VWM) of 128 V, meaning it remains in high-impedance blocking mode for continuous reverse voltages up to this level. This rating provides a 17.5 % margin below its minimum breakdown voltage (143 V), ensuring stable operation under normal conditions while allowing reliable triggering during transients. The P6SMB150AHM3/I's VWM is tested at 25 °C and derates predictably with temperature per the published thermal curves.
Does the P6SMB150AHM3/I have a bidirectional variant?
No, the P6SMB150AHM3/I is strictly unidirectional, as indicated by the "A" suffix and absence of "CA" in the part number. Bidirectional variants (e.g., P6SMB150CAHM3/I) exist in the same series but feature symmetrical clamping in both directions and no polarity marking. The P6SMB150AHM3/I uses a cathode band for orientation and must be installed with correct anode/cathode alignment to function as intended in DC-coupled protection circuits.
What package type does the P6SMB150AHM3/I use, and what are its key mechanical features?
The P6SMB150AHM3/I uses the SMB (DO-214AA) surface-mount package, measuring 3.94 mm in length, 2.20 mm in height, and featuring matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its molding compound meets UL 94 V-0 flammability rating, and it is rated MSL Level 1 with a maximum reflow peak temperature of 260 °C. The P6SMB150AHM3/I's compact size supports high-density PCB layouts while maintaining 600 W pulse capability when mounted on 0.2" × 0.2" copper pads.
